#现货与合约策略 Bitcoin ($BTC) is a decentralized digital currency, introduced by Satoshi Nakamoto in 2009. It is based on blockchain technology and verifies transactions through a peer-to-peer network, without the need for banks or third-party intermediaries. The total supply of Bitcoin is limited to 21 million, giving it scarcity, and it is often referred to as "digital gold." Its decentralization, resistance to censorship, and ease of cross-border transfers have attracted a large number of investors and institutions. However, significant price volatility, high energy consumption, and regulatory uncertainty are also challenges it faces. Currently, Bitcoin is gradually being recognized in the global financial system and is becoming an important digital asset.
